1. I know Hungarian and Rumanians cannot stack but they should be able to rail move through each other. For example, just because a Rumanian SEC unit garrisons a city should not prevent a Hungarian unit from using rail movement through that city and vice versa.
2. Helsinki is still showing up as needing garrisons to prevent partisans when option 'shift K' is used to highlight garrison city colors.
3. When Army Group South turns into A + B, you need to provide another Luftflotte HQ so both A + B have higher HQ's for attaching air units. The old South HQ Luftflotte should become the air HQ for A and a new one generated for B.
4. Disbanding a unit should not count as a destroyed unit - specifically forts.
5. Units that are completely surrounded by enemy units should not rout but should surrender even if they are not isolated for 1 turn.
6. Could we have a button, that when selected, shows ONLY withdrawing units on the map. Trying to find them is sometimes difficult.
7. An option under Air Doctrine that allows us to set a minimum air unit operational strength % which, when the unit goes below set strength, automaticaly sends it to the National Reserve. This would help with the micromanagement of checking each unit strength and manually sending it back to the reserve when it goes below a desired strength. Might also prevent all those cases of units remaining operational with only a couple of A/C that can't be sent to the Reserve but only have the Disband option available.
